The fact that wide receiver (or slotback) Chris Bauman won't play next year with the Cats isn't a surprise. He didn't gain a lot of yards on the season, but was hot for a few games at the end of the season (including five catches for 108 yards in the playoff game against the Argos), which was enough to get other teams interested in him. Certainly Bauman would have been an upgrade to the Argos last season at non-import receiver, although whether quarterback Cleo "the Party" Lemon would have used him is questionable.
Gauthier as a non-import tackle was getting older and probably a victim of Obie's "better is better" mantra. Going with two import tackles is certainly more popular recently, although I'm not always sure the use of an import spot on a second tackle is smart. We'll see what happens at camp.
